Enabling the service

To update Google+ through text messages, you will have to initially add your phone number in Google+ settings, following which Google will text you a verification code which has to be added in the Google+ settings. Optionally, you can also add a security PIN for extra security and avoid spoofing of text messages.

Further, you can also modify the notification settings so that you can be notified by any specific activities on Google+ such as mentioning your name, commenting on your post, adding you to a circle, tagging you in a photo and more.

While these notifications are also available to US users, Indian users get the additional benefit of being able to post into their Google+ stream by texting a message to 9222222222 at no extra cost. This update will be visible to all your circles by default and you will be charged as per the standard message rates from your carrier.

You can also have better control of your posts by sharing them with only specific people or circles, by using a few short codes which can be appended to your text messages:

@[circle name]
To share with a specific circle, append your post with @[circle name]. For example: “Will see you at the game @soccerfolks”.

@[email address]
To share your post with a specific person, append your post with @[email address]. For example, “In SF for the week @jazzguitar9@gmail.com” will be visible to jazzguitar9@gmail.com.

Quite honestly, it does make a lot of sense to offer SMS posting capabilities to Indian users since smartphone penetration is still pretty low and a lot of users still rely on SMS to converse with their friends/family.

That aside, Facebook has also tried to tap into this market over the past few years with several initiatives such as Facebook Zero and Facebook text messages, but it has very few mobile operators onboard whereas this SMS feature from Google seems to be carrier-agnostic, which could provide an competitive advantage to Google in the forthcoming months.
